The PEPs exist as a way to formalize important debates and hard decisions.
Without a PEP that offers a formal description of the changes, it is hard to
have a reasonable debate.  I would not be comfortable with the specification
for any feature from stackless being the implementation.

Given the current release schedule for Python 2.0, I don't see any
possibility of getting a PEP accepted in time.  The schedule, from PEP 200,
is:

    Tentative Release Schedule
        Aug. 14: All 2.0 PEPs finished / feature freeze
        Aug. 28: 2.0 beta 1
        Sep. 29: 2.0 final
